Kontorslokaler nyttjas generellt cirka 2500 av årets 8760 timmar. Ett vanligt problem med kontorslokaler är det termiska klimatet, antingen är det för varmt, för kallt, eller så drar det. Höga temperaturer, över ca 26°C, bidrar till trötthet, nedsatt koncentration och gör att luften känns mindre fräsch. Stora variationen av lasten mellan dag och nattetid kan också resultera i att lokalerna överventileras under nattetid och underventileras under dagtid. Syftet med examensarbetet var att undersöka och jämföra Ecoclimes komforttaks lösning med andra olika värme och kylsystem i kontorslokaler. Att undersöka vilka eventuella fördelar Ecoclimes komforttak har gällande komfort, kyla, ventilation och ur energisynpunkt. Simuleringsprogrammet IDA ICE har använts för att simulera komforten och rumstemperaturer för ett kontor och ett konferensrum i en byggnad placerad i centrala Umeå. Resultaten från simuleringar indikerar att Ecoclimes komforttak, sänker den operativa temperaturen och höjer komforten med en mindre andel missnöjda i sitt rum jämfört med andra system trots samma rumstemperatur. För att bedömma andelen missnöjda i ett rum har komfortindexet PMV(Predicted mean vote) och PPD(Predicted percentage dissatisfied) använts. Den höga passiva effekten bidrar också till mindre energianvändning av ventilationsfläktar ifall ett VAV-system med rumstempertaurreglering används. Vidare har en känslighetsanalys genomförts på komforttaken där det undersöks hur kyleffekten påverkar kyltider, temperatur och komfort. Känslighetsanalysen visar att en ökning eller minskning av kyleffekten med 10% påverkar resultaten mest under en mycket varm dag jämfört med en normalvarm. Skillnaden i komfort var dock liten, endast 0,2 procentenheter från grundfallet

Memory profiling is an important technique which aids program optimization and can even help tracking down bugs. The main problem with the current memory profiling techniques and tools is that they slow down the target software considerably therefore making them inadequate for mainline integration. Ideally, the user would be able to monitor memory consumption without having to worry about the rest of the software being affected in any way. This thesis provides a comparison of existing techniques and tools along with the description of a memory profiler implementation which tries to provide a balance between the information it is able to retrieve and the influence it has on the target software

The present dissertation deals with the artistic collaboration of a married couple, Charles Rennie Mackintosh and Margaret Macdonald. Living in Glasgow at the turn of the century, theeå, Swedeny concentrated their work on interior design. However, artistic collaboration has been neglected by traditional art history, with its concentration on individual creativity. For the couple in question, this has meant that the work they created together has been mainly attributed to Mackintosh, thereby relegating Mac­donald to the role of spouse and assistant, rather than co-creator. The present disser­tation presents a different picture of the couple's collaboration, challenging and revi­sing our cultural perceptions about the creative abilities of the respective sexes. A selection of interiors created by the Mackintoshes is studied in order to shed light on their collaborative efforts. The analyses embark from the perspectives of «masculine» and «feminine» in order to show how the Mackintoshes created artistic wholeness in their interiors, while at the same time opening up the spaces for a mixture of actors, i.e. making the rooms accessible to men and women alike through their designs. During this epoch, the concepts of «masculine» and «feminine» were employed as natural points of reference in an attempt to explain social and cultural phenomena scientifically. The Mackintoshes made use of the era's conventions when creating interiors in the accepted division of masculine (hallways, dining rooms, libraries) and feminine (bedrooms, salons) spaces. However, with time they began to combine these accepted gender forms in order to create something new and modern. Just as the Mackintoshes could create more powerful works of art by combining their respective artistic talents, their spaces could accrue greater significance through the combination of masculine and feminine principles.digitalisering@um
